Hello!
First, find angle BOA on the protractor. To do this, look for point B, point O, and point A.
Now, we see some markings that mark what degree point B and point A are at. Point B is marked at 60 degrees, and Point A 40 degrees.
Now, all that's left to do, is subtract the two measurements.
60 degrees - 40 degrees = 20 degrees
Therefore, your answer is 20.
Hope this helps!
Answer:
Slope is 5.
Step-by-step explanation:
y + 3x = 8x -7
y = 5x - 7
coefficient in front of x is the slope/rate of change once you get the equation slope intercept for y = mx + b. m is the slope.
Answer:
D. 4x-3
Step-by-step explanation:
First you subtract the 7x and 3x to get 4x.
Then you subtract the -5 and the -2 to get -3
Therfore, your answer is D
The formula to find the slope of a line is

I'm not sure if my fraction looks right, so I'll add it in a separate attachment too.
